OK, here is another issue that I am sure everyone has had to deal with at one time or another. Have this customer for two seasons, always pays, never really had any problems, till two weeks ago. After mowing, I was going around with the weed whip and saw I must have chopped a head off one of the sprinklers. I spoke with the customer and told him that I didn't see it and it must not have recessed all the way that morning, but unfortunately if they don't go down all the way and accidently get cut, it really isn't my fault and that he should contact his normal sprinkler guy to replace the head. He said that this season has been the worst he has ever had with having sprinkler head not working or being damaged and that it must be the way I am mowing or my machines. I told him the truth, he is about the only customer I have that seems to be having a problem ( has had to replace two other heads so far this year and both were reinstalled about an inch higher than the previously existing grade) and that he will need to have the heads lowered. Either I can do that or he can have someone else do it but in order to avoid any issues with mowing and trimming, the heads ALL have to be installed at or slightly below grade. This week I showed up and he had every head on his property with a stake next to it and wants me to mow around each of them and then go back and weed whip around them ... I told him that is that is what he wanted it would take more time and he would ahve to give me a few more dollars for the time and inconvenience ... he flatly refused, claiming he has "had a thousand landscapers mow his lawn over the years and that I am the first one to cause problems with his sprinkler heads". It is my opinion that if a customer has an "underground" sprinkler system, that unless the system is opperating, that all head in the lawn areas should be "underground"!!! If they are not installed at or slightly below grade or if they don't go back down all the way after that zone finishes, I really can't be held responsible. The customer hasa few options to get the real problem remedied ... pay me to lower them, pay his sprinkler guy to do the same, do it himself, or keep paying to have the heads replaced .... anyway you look at it there is time and money involved. How many of you have had similar situations and what have you done to solve this dillema?
